I just got done with active shooter training at my workplace, and we're always told to not be the hero, and to wait for the police. That's always been against my instincts, and uvalde confirmed that. What greater love do we have for our fellow people than to die saving them? I think it is better to be trained to go against the person, have a firearm if possible, but when you're trained to hide, you become a target. I'm not an expert by any means.But intuitively, it is wrong to just hide and let other people get shot.
